When elements of a #foodchain are lost, this can have #ecologicalimpacts with other species getting more abundant. N. Hammerschlag et al. (2025) report a sharp #decline in the #whiteshark population in #FalseBay, South Africa, possibly due to attacks by #orcas. This has implications for Cape fur seals and sevengill sharks.

Is there anything that #humans don't destroy or harm on this planet?

"At the current rate of decline, which is 7.9 percent annually, the African penguin will go extinct in the wild by 2035."

And I'm still the #child, will remain so, in relation to #nature.

New clam species discovered in South Africa's #kelp forest https://phys.org/news/2024-07-clam-species-south-africa-kelp.html paper: https://zookeys.pensoft.net/article/124517/

This small #clam, which is only 2 mm in length, spends its life crawling between the spines of #SeaUrchins. The #NewSpecies has so far only been found in one locality in #FalseBay, #SouthAfrica, where it was found attached to the burrowing #SeaUrchin Spatagobrissus mirabilis in coarse gravel at a depth of about 3 m. It has not been observed free-living, without the host urchin.
